This diff introduces a new protocol identifier `NFT\0` (`0x4E465400`) to be used in OP\_RETURN outputs within the NFToa ecosystem.
The protocol defines a consistent output pattern:
```
[OP_RETURN] [NFT\0] [OP_FALSE] [message] [nonce]
```
* **`[NFT\0]`**: 4-byte protocol ID uniquely identifying NFToa transactions.
* **`[OP_FALSE]`**: reserved marker enabling distinction of protocol metadata from other payloads.
* **`[message]`**: variable-length UTF-8 or binary payload containing application data (e.g. NFT access metadata, transaction context).
* **`[nonce]`**: a random or sequential value ensuring uniqueness and preventing replay collisions.
All NFToa applications will adhere to this pattern to maintain consistency, simplify parsing, and enable brand-specific rendering (e.gUpdates the protocol identifier table by formalizing the spec details for the new NFToa Protocol ID. logo display in Cashtab).
This ensures NFToa protocol messages are clearly distinguishable on-chain while remaining compatible with existing OP\_RETURN parsing standardThis revision ensures the on-chain data is correctly mapped to the protocol's official display name and authors.
A complete and detailed specification for the NFToa protocol, including all technical requirements and usage guidelines, has been added to 'nftoa.md'.
